Unable to build R-2.10.0 and later releases on AIX 6.1

Hi,

I have been able to build R-2.9.2 on AIX 6.1 and AIX 5.2. However, I
failed to build R-2.10.0 and later releases on these AIX platforms. The
error messages I got are attached below:

"connections.c", line 461.10: 1506-022 (S) "truncate64" is not a member
of "struct Rconn".
"connections.c", line 772.10: 1506-022 (S) "truncate64" is not a member
